← HistoryWhich consequence occurs when an early medieval lenses are severely misaligned?
A)Higher-order aberrations become visually noticeable✓
B)Chromatic aberration can be eliminated fully
C)Spherical projection becomes perfectly linear
D)Internal reflection generates stable Airy disks
💡 Explanation
Higher-order aberrations become apparent in early lenses because of imperfections in manufacturing cause increased wavefront distortion via Seidel aberrations. Therefore, image quality degrades significantly, rather than improving, because manufacturing accuracy was the limiting factor.
